test position from lc0-stockfish

Post by Uri Blass » Sun Jan 10, 2021 10:36 pm

position is from the following game
https://www.chess.com/a/3CF6AcNyC2Ra7x

I was surprised to see that chess.com claims that 16.f5 of lc0 is a mistake because my stockfish claims that white has a big advantage after 16.f5 so I decided to analyze the previous moves with stockfish and it seems that 14...Qf5 was a mistake of stockfish and the correct move was 14...b5
I am not sure if 14...b5 is good enough for a draw and maybe I did not analyze for enough time and the mistake was earlier but it seems with 2 options stockfish see that 14...b5 is best with 0.00 evaluation and second best move is 14...c5 with 1.8 pawns for white.
